MAX6225/MAX6241/MAX6250 Low-Noise, Precision, +2.5V/+4.096V/+5V Voltage References General Description Features Low 1.0ppm/C Temperature Coefficient The MAX6225/MAX6241/MAX6250 are low-noise, Very Low 1.5V Noise (0.1Hz to 10Hz) precision voltage references with extremely low 1ppm/C P-P temperature coefficients and excellent 0.02% initial 0.02% Initial Accuracy accuracy. These devices feature buried-zener technology 15mA Output Source and Sink Current for lowest noise performance. Load-regulation specifications Low, 18mW Power Consumption (MAX6225) are guaranteed for source and sink currents up to 15mA. Industry-Standard Pinout Excellent line and load regulation and low output impedance Optional Noise Reduction and Voltage Trim at high frequency make them ideal for high-resolution Excellent Transient Response data-conversion systems up to 16 bits. 8-Pin SO Package Available The MAX6225 is set for 2.500V output, the MAX6241 is Low 20ppm/1000h Long-Term Stability set for 4.096V output, and the MAX6250 is set for 5.000V Stable for All Capacitive Loads output. All three devices provide for the option of external trimming and noise reduction.
